379724 - Update of ANSI/ASCE/EWRI Standard Practice 44-13 (Supercooled Fog Dispersal)

Tuesday, June 5
8:30 AM - 10:00 AM
Location: Skyway Room

Fogs can pose a significant threat to public safety and quality of life. Extended periods of fog can have large economic impacts on the aviation, tourism, transportation, energy, and mining industries. The total annual weather impact on United States aviation is an estimated $3 billion for accident damage and injuries, delays, and unexpected operating costs. Weather is a primary contributing factor in about one (1) out of every four (4) aviation accidents. This presentation begins with an overview of the standard practice (ANSI/ASCE/EWRI 44-13) as developed by the ASCE/EWRI Atmospheric Water Management Standards Committee (AWM SC). The overview covers capability statements, an abridged version of the inherent physics, and implementation of supercooled fog dispersal operational projects. The author will end with a discussion for recommendations on future changes that may occur in the next version of this standards document. The approximate timeline to be used by the AWM SC to supplement or revise the current version will also be provided.
